Minute bars for timestamped comparisons
This page requests FMP one-minute historical bars for an index symbol. Each row contains open, high, low and close levels plus the provider's volume field when available. A minute is an aggregation interval, not a guarantee that every update is captured or that each displayed row is new. The lookup has no tick tape, order book or execution simulator.
A missing minute is an unknown observation
Suppose a hypothetical export has closes of 5,000 at 10:00 and 5,010 at 10:02, with no 10:01 row. The observed change is 10 points, or 0.20%, across the gap. It is not a measured one-minute return. Filling 10:01 with 5,000 would manufacture a zero-return minute and assign the entire change to the following row. That changes return distributions and can alter a rule using consecutive closes. Preserve the gap until its cause is understood.
A timestamp near a scheduled announcement also needs context. A bar labeled 10:00 could refer to a provider-defined boundary; this response does not establish its timezone or whether the label denotes the start or end of the interval. Do not claim a before-and-after news effect without resolving those conventions and checking whether the bar was complete.
Inspect a session before using it
- Choose the index and date range, then load the result. Blank dates use provider defaults. Reversed dates are rejected.
- Confirm the loaded symbol and range above the table. Refresh repeats that submitted request; editing a filter requires Load Data.
- Inspect timestamp ordering, duplicates, gaps and OHLC consistency. An absent row is not automatically a flat market or a trading halt.
- Export all returned rows. The file includes the symbol and 1min interval; table pagination only changes which 50 rows are visible.
Coverage and interpretation
The eight choices include U.S. equity benchmarks, VIX and several international indexes. Their sessions and construction differ. The menu provides lookup symbols, not a promise of all dates or a fixed number of weeks of history. VIX reflects expected volatility from S&P 500 options; it is not the price of a tradable stock basket.
An index is a calculated benchmark. Its provider volume should not be substituted for SPY, an index futures contract or the traded volume of individual constituents without a defined source methodology. Missing volume remains unavailable; a reported zero is preserved but is not interpreted as no underlying trading. No institutional-flow conclusion follows from this field alone.
One-minute cache is not one-minute latency
The current API caches these results for up to one minute. The page makes an initial request and responds to manual load or refresh actions; it does not stream new bars automatically. Provider delay, data availability and an unfinished current bar remain separate issues. Fetch time is when this page received data, not when the index last changed.
Use the export for analysis in a spreadsheet or your own program. It does not connect a data feed to TradingView, place a trade or establish that an entry could have filled at an index level. Any strategy test needs a tradable instrument, execution assumptions and costs in addition to these observations.
